■ Application
XLT transducers operate with Siemens SITRANS LU transceivers
in measuring ranges from 0.9 ... 60 m (1.8 ... 200 ft) and temperatures up to 150 °C (300 °F). A beam angle of just 5° provides
accurate readings in deep, narrow tanks.

With increased signal sensitivity, the XLT transducers from
Siemens can operate in difficult applications such as limestone,
cement clinker and hot stone. All models have a sealed
aluminum face to withstand very harsh environments.
Cable connection
2-core shielded/twisted, 0.5 mm²
(20 AWG), silicone sheath
Cable (max. length)
365 m (1 200 ft) with RG 62 AU
coaxial cable
During operation, EchoMax transducers emit acoustic pulses in
a narrow beam. The level transceiver measures the propagation
time between pulse emission and reception of the echo to
calculate the distance from the transducer to the material.
Temperature variations are automatically compensated by the
integral temperature sensor.
• Key Applications: bulk solids including limestone, cement
clinker, hot stone and coal bunkers
Certificates and approvals
CE (EMC certificate available on
request), CSAUS/C, FM, ATEX II

Definition of beam width: twice the angle at which the off-axis transmission
is 3 dB less than the acoustic pressure level of the transmission axis (as
measured equidistant from the sensor face).
